ERp29在结直肠癌中的表达及其临床意义

目的 研究结直肠癌中内质网蛋白29(ERp29)的表达情况及临床意义.方法 对62例结直肠癌患者病理组织切片,行ERp29免疫组化染色,统计分析癌组织及癌旁组织 ERp29表达情况,并比较不同ERp29表达水平的结直肠癌患者,其临床及病理特征差异有无统计学意义.结果 62例癌组织中ERp29表达阳性24(38. 7％)例,阴性38(61. 3％)例,癌旁组织阳性58(93. 5％)例,阴性4(6. 5％)例,癌组织 ERp29阳性组与阴性组之间,肿瘤的TNM分期以及淋巴结转移情况差异有统计学意义(P＜0. 05).结论 结直肠癌组织中ERp29的表达水平低于癌旁组织,ERp29的表达情况可为评估肿瘤转移倾向及预后提供一定参考价值.

Expression and clinical significance of ERp29 in colorectal cancer

Objective To investigate the expression and clinical significance of endoplasmic reticulum protein 29(ERp29) in colorectal cancer. Methods Paraffin-embedded sections from 62 cases of colorectal cancer tissues were obtained and used for immunohistochemical staining of ERp29. The clinical and pathological data of various levels of ERp29 in patients with colorectal cancer were analyzed to determine if there was a significant difference. Results The expression of ERp29 in 62 cases of colorectal cancer tissues, 24(38. 7％ ) cases were positive and 38(61. 3％ )cases were negative. The expression of ERp29 in 62 cases of adjacent tissues, 58 (93. 5％ ) cases were positive and 4(6. 5％ ) cases were negative. There was a significant difference in TNM classification and lymph node metastasis between ERp29 positive group and ERp29 negative group (P ＜ 0. 05 ). Conclusion Colorectal cancer tissues have significantly lower levels of ERp29 than adjacent tissues. ERp29 may be helpful to evaluate the metastatic proclivity and prognosis of colorectal cancer.
